+### Note on `github.repositoryUrl` property

+The `git://` protocol is disabled for security reasons. You will not be able to use the value of `github.repositoryUrl` to perform any git operations. Instead, you can use `${{ github.serverUrl }}${{ github.repository }}` to give you the HTTP URL for the current repository.

 ## `env` context
 
 The `env` context contains variables that have been set in a workflow, job, or step. It does not contain variables inherited by the runner process. For more information about setting variables in your workflow, see [AUTOTITLE](/actions/using-workflows/workflow-syntax-for-github-actions#env).
